Vanda plant named &#39;SPCDW1320&#39;

ABSTRACT

‘SPCDW1320’ is a distinctive variety of  Vanda  which is characterized by the light-yellow sepal and petal background coloration, purple spotting and a broad rim of purple on each of the sepals and petals, with the light yellow background being more prominent in the two lateral sepals than in the two petals and the dorsal sepal. The new variety is a  Vanda , typically produced as an indoor ornamental plant.

LATIN NAME OF THE GENUS AND SPECIES

The Latin name of the genus and species of the novel variety disclosed herein is Vanda hybrid.

VARIETY DENOMINATION

The inventive variety of Vanda disclosed herein has been given the variety denomination ‘SPCDW1320’.

BACKGROUND OF THE INVENTION

This application relates to a new cultivar of Vanda, as described in EU application number 2013/2929, filed Sep. 19, 2013, grant pending, to which applicant claims priority.

Parentage: The Vanda variety ‘SPCDW1320’ is the result of a planned breeding program. The new variety originated as a seedling from the crossing of the unpatented, proprietary seed parent Vanda ‘M58N’ with the unpatented, proprietary pollen parent referred to as Vanda ‘S399’. The crossing was made by the inventor in his research greenhouse in Chonburi, Thailand in October of 1999.

The new variety was first selected by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in February of 2005, in a research greenhouse belonging to the inventor in Chonburi, Thailand. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘SPCDW1320’, assessing stability of the unique characteristics of this variety.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘SPCDW1320’ was first performed at a commercial laboratory belonging to the inventor in Chonburi, Thailand by tissue culture in June of 2007. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, and tissue culture plantlets were in a laboratory belonging to the inventor, and not accessible to the public. Through subsequent propagation by vegetative cuttings, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1320’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SPCDW1320’. These characteristics in combination distinguish ‘SPCDW1320’ as a new and distinct Vanda cultivar:

1. Unique sepal and petal coloration, namely a light yellow background with purple spotting and a broad rim of purple of each of the sepals and petals; and,

2. A unique light yellow background being more prominent in the two lateral sepals then in the two petals and the dorsal sepal; and,

3. Very dark purple floral lip.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary plant of ‘SPCDW1320’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. This plant is approximately 5.5 years old, shown planted in an 8 by 8 cm container.

FIG. 3 illustrates, in full color, the typical flowers of ‘SPCDW1320’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements describe ‘SPCDW1320’ plants grown in a greenhouse in Honselersdijk, the Netherlands. Temperatures ranged were approximately 23 degrees Celsius during the day and 19 degrees Celsius at night. No photoperiodic or chemical treatments were given to the plants. When natural lighting fell below 150 Watt, artificial lighting is given at 10,000 lux for 16 hours a day. Measurements and numerical values represent averages of typical plant types.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘SPCDW1320’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2007 edition. A botanical description of ‘SPCDW1320’ and comparisons with other varieties of Vanda are provided below.

The new variety, however, produces     flowers with a different color and color pattern than the seed     parent. Plants of the new cultivar ‘SPCDW1320’ are similar to the     pollen parent, Vanda ‘S399’ in most horticultural characteristics.     Plants of the new variety, however, are smaller, with a longer leaf     span than the pollen parent. -   Comparisons with other commercial Vanda: ‘SPCDW1320’ is similar in     most horticultural characteristics to the patented commercial     variety Vanda ‘Blue Magic’ in most horticultural characteristics.     The new variety, however, produces sepals and petals of which the     coloration is a light yellow background with purple spotting and a     broad rim of purple of each of the sepals and petals, the light     yellow background being more prominent in the two lateral sepals     then in the two petals and the dorsal sepal, whereas ‘Blue Magic’     produces petals and sepals that are white with thick, dark purple     netting. The new variety has flowers which are similar in size as     ‘Blue Magic’. 

That which is claimed is:
 1. A new and distinct variety of Vanda plant named ‘SPCDW1320’, substantially as described and illustrated herein.
